Patented Jan. 7, 193% UNITED STATES PATENT OFFICE WILLIAM J. CAMPBELL, 0F INDIANAPOLIS, INDIANA, ASSIGNOR TC AMERICAN SLICING MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPO RATION OF NEW YORK snrcme macn'znn Y Application filed April 13, 1928, Serial No. 269,683. Renewed June 8, 1929.

My invention relates to a slicing machine having a rotary knife and a carria e for moving the work past the cutting e go of said knife. The particular object of my invention is to provide an improved pusher plate for use with such arriage. ()ne object of my inventionis t provide a pusher plate adaptable for use with a carriage the main extended supporting surface of which lies in a horizontal plane, although theapplication of my pusher plate is not intended to be limited merely to such application. Another object is to provide a pusher plate and guiding means therefor which shall have a minimum tendency to bind and which shall permit the pusher plate to be moved toward and away from the gauge plate with maximum ease and speed. c

Other objects will appear from' time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically ings, wherein Figure 1 is a rear elevation;

Figure 2 is a fragmentary top view with parts in section; and p Figure 3 is a sideelevation.

Like parts are indicated by like symbols throughout the specification and drawings.

A indicates anysuitable slicing machine base member having the ground engaging supports or studs A. B generally indicates any suitable housing member or body. upwardly projecting therefrom having associated therewith a face plate B normally fixed in position and a gauge plate B? which may be moved toward-and away from the plane of the knife as for example by rotation of the knob 13*. I do not wish to be limited to any particular means for imparting movement to the gauge plate but I have herein shown lugs B on the rear of the gauge plate, levers or arms B pivoted thereto, themselves pivoted as at B, a gear B associated with one of said levers and a worm B in mesh therewith and actuated by the whereby the carriage may in the. accompanying drawa supplemental guiding as vertically aligned, although this arrangeends upon the supports D Beneath it is.

a supplemental trackvD herein shown as of rectangular cross-section. D indicates a carriage slidable along the track I) and providedi with a downward extension l) formed to surround the track D and thus to prevent rotation of the carriage l) about the track D. D is any suitable anual handle lid moved along the track D.

E indicates any suitable carryingtray positioned upon the carriage D The tray E is .here shown as having an extended lane suporlzontal porting surface E lying in a plane; E indicates an upward extension from one side of the carriage plate E and is herein shown generally at right angles'to the portion E and is supported upon the upward extension E from the carriage.

- There is a further extension E on which are mounted the main guiding pins E and the ment, while preferable,-is not necessary.

G indicates the pusher plate proper having generally to the member E Gr isfany suitable fiber or'other anti-frictional support, whereby the lower edge of the pusher plate pin E herein shown a lower edge G conforming generally tothe surface E and a lateral edge Gr conforming is spaced slightly above the su-rface'E and whereby the wear and rattling of the opposed parts is reduced to a minimum. G is any suitable knob adapted for the. manual'actuation of the pusher plate'G. G indicates a lateral extension from the pusher plate associated with which is a downward outer extension G which is provided with a main bearing sleeve G and a' supplemental bearing sleeve G? through guiding pins E and E respectively.' It will be observed, from Figure 3, that the distance separating the sleeves Gr Gr islless than the length of the sleeve G. The length of the sleeve G in relation to the span between the two sleeves,

and thus between the two guiding members v showing.

E E penetratingthe sleeyes, insures a minimum of binding, and maximum ease in moving the above described usher plate. It will be observed that the h ight ofthe member E is such as to permit the member G to extend outwardly over its upper edge, the ortion G Wl'l3l1 its bearings G G dependmg to alignment with the guiding pins E and E It will be realized that whereas I have de:

scribed and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts Without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific The use and operation of my invention are as follows:

In the employment of a broad extended and, in the form of the device herein shown, a horizontal support, such as the member E, it is desirable to provide guiding means for a pusher plate which shall have a mini-.

the supplemental guidepin E passing there- 7 through. Owing to the short length of the sleeve G and to the short distance separating the pins E and E in relation to the ?length of the bearing G, no troublesome degree of binding can'take place and the face plate moves smoothly along the guiding pins. In effect the pin E and its opposed bearing G are the real guiding-members, while the pin E and its guiding bearing G merely prevent rotation of the pusher plate in relation to the bearing G.

It will be noted, as clearly illustrated in Figure 3, that the position, length and shape of the main bearing sleeve Gr issuitable for its use as a handle for the pusher plate and the regular handle G may be eliminated. The bearing sleeve may be employed for operating the movable or slidable carriage D and at the same time be used for sliding the pusher plate, and thus the' carriage handle 5 may also if desired be dispensed with.
